Abstract
PURPOSE: To manufacture a high hardness die having high-precision fine convex patterns by forming a thin conductive layer through electroless plating treatment on the fine concave patterns formed through etching on the surface of an Si single crystal substrate then performing electrochemical molding.
CONSTITUTION: Fine concave patterns 35 are formed on the surface 31 of an Si single crystal substrate 32 having a flat surface, by the etching treatment using striplike masks 33 for etching. Next, a conductive substrate 36 is secured to this substrate 32 by using a conductive adhesive agent 37, and in this state, a thin conductive layer 40 is stuck by electroless plating treatment on the surface 31 of the substrate 32. Next, in electrolyte 41, electrochemical forming is applied on the surface 31 of the substrate 32 having formed with the fine concave patterns 35, whereby a thick metal layer 45 of high hardness is formed. Thence, the metal layer 45 is peeled from the substrate surface 31 and is taken out as the die for forming having the surface 48 formed with the fine convex patterns 47 corresponding to the patterns 35, after which the circumference of the layer 45 is subjected to working.
